Meeting Room Acoustics & Speech Privacy
Meeting rooms commonly experience two types of acoustic problems. The first is excessive reverberation, where sound reflects off hard surfaces, making video calls and group discussions tiring and difficult to follow. The second is poor sound insulation, where conversations can be heard through glazing, partition walls and doors, creating concerns around confidentiality. In some meeting rooms, both problems occur together. These are separate acoustic issues that require different solutions, and addressing one will not necessarily resolve the other.
Speech clarity and speech privacy are two different aspects of meeting room acoustics. Speech clarity relates to how easily people within the room can understand one another. This can be improved by introducing sound-absorbing wall panels and ceiling treatments to reduce reflected sound and reverberation. Speech privacy, on the other hand, concerns preventing conversations from being understood outside the room. This depends primarily on the sound insulation performance of partitions, glazing, doors and seals, and may also benefit from sound masking in surrounding areas. A meeting room can have excellent speech clarity but poor privacy, or vice versa. Understanding both is essential before recommending an appropriate acoustic solution.
What Does an Acoustic Survey Involve?
An acoustic survey assesses the existing performance of the meeting room to identify the causes of any acoustic issues. This can include measuring reverberation time (RT60), which indicates how long sound remains in the room after the source has stopped, and speech intelligibility (STI), which assesses how clearly speech can be understood. The survey can also investigate potential sound transmission paths, including glazing, partition walls, doors and gaps around frames, to establish where noise may be entering or escaping the room.
What Can Acoustic Treatment Achieve?
Acoustic wall panels and ceiling treatments can significantly improve the internal acoustic environment of a meeting room by reducing reverberation, improving speech clarity and making conversations and video calls more comfortable. However, sound absorption should not be confused with sound insulation. Where confidentiality is a priority, such as HR meetings, client discussions or board meetings, acoustic panels alone are unlikely to provide the required level of speech privacy.
In these situations, additional measures may be necessary, including improvements to partition construction, acoustic doors, perimeter seals or glazing. At Torann Acoustics, we assess the specific requirements of each room and provide clear advice on what acoustic treatment can realistically achieve. Where improvements to sound insulation are required beyond the installation of acoustic panels, we will explain the available options rather than recommend a treatment that will not address the underlying problem.
Frequently Asked Questions
Will acoustic panels make our meeting room soundproof?
Acoustic panels are designed to absorb sound within a room rather than prevent sound from travelling through walls, glazing or doors. While they can significantly reduce reverberation and improve speech clarity, they do not provide effective sound insulation on their own. If the objective is to prevent conversations from being heard outside the meeting room, additional measures such as upgraded partitions, acoustic doors or improved seals may be required. We can assess these requirements during an acoustic survey and recommend suitable solutions.
Do you offer sound masking as well as acoustic panels?
We can advise on the use of sound masking alongside acoustic wall and ceiling treatments. Sound masking introduces a controlled background sound to help make conversations less intelligible in adjacent spaces, while acoustic panels reduce reflected sound within the meeting room. These approaches address different acoustic problems and can be particularly effective when considered together. For more information, read our guide to sound masking vs. sound treatment.
